Metre Ruler and Table tennis.
Aim: Our aim is how far the ball bounces back in different heights.
Hypothesis: Will the ball bounce higher if you let it go on a higher height or will the ball bounce lower?
Method:
1. Set a metre ruler, from the bottom to the top.
2. Drop the ball from a certain height, near the ruler.
3. Measure it, and record it.
4. Test the same height three times, to get the correct height.
| Heights | 1 | 2 | 3 | Average |
| 2m | 21 cm | 20 cm | 21 cm | 20.6 cm |
| 1m | 18 cm | 17 cm | 19 cm | 18 cm |
| 0.5m | 8 cm | 9 cm | 9 cm | 8.6 cm |
| 1.5m | 20 cm | 19 cm | 20 cm | 19. 6 cm |
Discussion: I believe that if you drop it in a high height it bounce more, this table goes up when it gets a higher number or height.
Conclusion: The higher you drop the ball the higher it bounce up. My hypothesis was correct.
